Trajan's Column

As you invoke the name of your Deity and beseech their aid, divine light washes out from you and coalesces into a 10 foot tall pillar of radiant flames in a 5 foot space within 120 feet of you. While the pillar is standing, it glows with divine daylight in a 30-foot radius. Creatures of your choice that enter or start their turn in that radius heal 10 hit points and are immune to Charm and Fear effects and have advantage on all saving throws. In addition, when a devil, fiend or an undead hits an affected creature with a melee attack, the aura flashes with brilliant light. The attacker must succeed on a Constitution saving throw or be blinded until the spell ends.
